Problems with car starting in the morning when it's cold.

In the morning when the car is cold, I turn the key and the car doesn't want to start. After turning the key attempting to start the car several times it starts. When the engine is warm/hot it starts with no problem. What is causing this problem?

The fuel pressure regulator might be the problem. the fuel system should have a higher pressure when cold to help warm the system. after that it is ok until cold again. Ever notice how the engine runs slightly faster when cold then slows down, this is why.

Or you might have moisture in your tank and lines... or if this is a high
mileage motor. You could have carbon deposits built up on the pistons
and intake valves... the make also cause rough idling. Hesitation when
you jump on it. And hard starts... look into some seafoam...
